Title: Optical switch and its production
Inventor: YOKOMACHI HIROYUKI
IPC: G02F1/313
Filed: 1994-08-10
Abstract: PURPOSE:To provide an optical switch which executes the switching action based on electrochromism by using optical waveguides having good light transmission characteristics, and a process for producing this optical switch. CONSTITUTION:The optical waveguides 20, 21 doped with Ti are formed by having an optical coupling part in proximity to each other on the surface region of a substrate 10 formed out of LiNbO3. An electrode layer 30, refractive index varying layer 40 and an electrolyte layer 50 are successively laminated and formed on this optical coupling part. The electrode layer 30 and the electrolyte layer 50 are respectively connected via lead wires 70, 71 to an external voltage source not shown in the Fig. The refractive index varying layer 40 is formed out of WO3 having a refractive index below the refractive indices of the optical waveguides 20, 21 in accordance with sputtering conditions under which the ratio of the partial pressure of O2 occupying in reactive gases formed by mixing Ar and O2 to the total pressure of these reactive gases is <=0.2. The refractive index varying layer 40, therefore, changes the refractive index in a range extremely approximate to the refractive index of the optical waveguides 20, 21 and has the absorbance lower than heretofore.

Title: Bubble memory device
Inventor: KAMEI SHINJI
IPC: G11C11/14
Filed: 1982-10-28
Abstract: PURPOSE:To speed up both reading time and writing time by providing an index register to store the position of an index mark and calculating the number of magnetic revolutions of a bubble memory device from the value of said index register for reading and writing of a desired page of the memory device. CONSTITUTION:The shift of an inex mark page from a replicating position is stored in an index register 11 in terms of number of revolutions. A necessary revolution number P which is needed to move a page (n) to be read out up to the replicating position is obtained from specific equation. Therefore the page (n) reaches the replicating position by giving P revolutions to a bubble memory device 10 in a rotating magnetic field. Then the bubble is replicated and transferred. The revolutions of the device 10 are kept as they are to carry the bubble to a detector, and the bubble is converted into the logical information. The device 10 is stopped after having the sum of number of revolutions S and P needed for the last bubble to pass through the detector. In this case, the value of the register 11 is replaced. In such a way, the present page position is stored in the register 11, and the necessary number of revolutions is obtained for read-out of the desired page from the value of the register 11. This reduces the reading time of a bubble memory device.
